Yes, i did do the coordinates again. I have a feeling I'll be going in and scheduling a training class. bah!
The ends are actually a separate piece. They're jump rings. I think he got them there or at a hardware store.They're 1/2" across. They remind of those keyrings that you spread apart to put the keys on.
The way he made them....he slipped the little black thing ( the wire leader connector sleeves) onto the wire, looped the wire thru the jump ring, then ran the little black thing back up to cover the end and hold it tight.
Good luck -- I know he's saved ME a fortune!!! LOL
